Reinforced Masonry - Axial Load
Reinforced Masonry - Axial Load
(OP)
I am studying for the SE exam to be taken next month and took a refresher course in Masonry.
The instructor when checking fa < Fa, used fa = P/An, or the axial load over the gross area of the column. Also (on another subject) when transforming steel in compression uses Ats = As(n-1).
The SERM examples when checking fa < Fa, use P/At, or the axial load over the transformed area of the column. When transforming steel in compression uses Ats = As(2n-1) to account for creep.
My question, which is correct?

2n-1 is used for long term loading
n-1 is used for other than long term loading

fa = P / An
or
fa = F/ At
